Honeywell Thermal Solutions FSG RM7840M1017 Burner Control

The FSG RM7840M1017 Burner Control from Honeywell Thermal Solutions is a microprocessor-based, integrated burner control engineered for reliable safety and precise firing. It manages pilot and main flame sequences with a 4/10 second pilot establishing period and a 10-second intermittent main phase. This interrupted-pilot control supports gas, oil, coal, or a combination for a single burner, delivering automatic burner sequencing and flame supervision. Rated for 120 Volt AC at 50/60 Hertz, its compact enclosure measures 5 inches wide by 5-1/4 inches deep by 5 inches high, helping fit tight control panels. Approvals include UL, CSA, FCC, CSD, SRE, and FM.

Designed for easy integration into industrial boilers and furnaces, the RM7840M1017 features built-in system status indication, self-diagnostics, pre-ignition checks, and early spark termination to prevent misfires and reduce energy usage.
